The reduced update stems from the third-quarter 2012 market basket forecast by IHS Global Insight, a financial forecasting firm that the CMS uses to identify market costs.
The rate boost still will increase payments next year at the 5,726 kidney disease treatment facilities to $8.4 billion, the CMS estimated.
The 301-page final rule also laid out specifics of a quality incentive program, which aims to improve care quality and patient outcomes. The rule specified that the CMS will use 2013 performance scores on the QIP measures for a broader range of patients to calculate dialysis facilities' payments in 2015.
Next year marks the third year of the four-year transition to a new ESRD payment system, although 90% of such facilities previously opted to receive payment entirely under the new system, according to the CMS.
About 20%, or 1,093, of ESRD facilities will likely face payment reductions of up to 2% in 2015 under the rule's final QIP measures, the CMS estimated.
The final rule also implemented a provision in the Middle Class Tax Relief and Job Creation Act of 2012 that reduces bad debt payments for certain Medicare providers while removing a cap on bad debt reimbursement to ESRD facilities.
